I'm working on a runtime reflection library, so there won't be 
any access to the actual type. Any access to constructors will 
have to be done through an interface like these:

class Struct : Reflection {
     size_t size() const;
     void construct(void[] mem);
}

class Class : Reflection {
     Object createInstance() const;
}

The library is basically done, but needs polishing. Also, I'm 
stuck waiting for things like __traits() being allowed to bypass 
protection, which was recently decided upon, but not yet 
implemented (hopefully this hasn't been overturned again).

   Thanks
